6 FAQs about [Three-phase photovoltaic inverter phase-locked loop]

What is a phase-locked loop control strategy for a grid-connected photovoltaic inverter?

Based on that, a phase-locked loop control strategy for the grid-connected photovoltaic inverter is designed on the customized IP core technology of FPGA. The strategy realizes real-time tracking and adjustment of the phase difference between the photovoltaic inverter system and the grid.

What is a software phase locked loop (PLL)?

Software Phase Locked Loop Design Using C2000 Microcontrollers for Three Phase Grid Connected Applications (Rev. A) Grid connected applications require an accurate estimate of the grid angle to feed power synchronous to the grid. This is achieved using a software phase locked loop (PLL).

What is phase-locked loop synchronization?

Typically, phase-locked loop (PLL) synchronization techniques are used for the grid voltage monitoring. The design and performance of PLL directly affect the dynamics of the RES grid side converter (GSC).

What is phase lock loop?

For achieving this synchronism, we require a control technique called phase lock loop. PLL is a closed-loop technique, and it produces an output signal which is synchronized in phase and frequency of the input reference signal. Every PLL has three common blocks—phase detector, loop filter, and voltage-controlled oscillator .

How to build a 3 phase inverter?

For the development of a prototype, a three-phase IGBT based inverter is built using Semikron Modules. The IGBT is driven by the Semikron SKHI22A gate driver circuit with the switching frequency of 20 kHz. To measure the voltage and current of the inverter and grid, LV25P voltage transducer and LA55P current transducer are used.
